BEx Runtime and BEx Tools from SAP BW 3.5 (deleted)
Use
The BEx tools from version SAP BW 3.5 are no longer available in SAP NetWeaver 7.4.
It is still possible to execute queries defined with BEx Query Designer 3.5 by using the analytic manager from SAP BW 7.4. A migration is required for BEx Analyzer workbooks and Web templates however. For more information, see Cookbook for Migration to BEx 7.0 in SAP Note 1807522
